In the said structure, said sheet cutter are centered close on the perpendicular bisector of two supporting rollern lines of centres.
In the said structure, said outer lever rod end is divided into two poles, and the roller of two pole rod ends is symmetrical in alignment of shafts axis and is installed in the sliding sleeve outer wall annular groove.
The utility model compared with prior art has following good effect:
1. the sheet cutter cut, during cutting smear metal less, reach residual impurity amount requirement in the pipeline easily.
2. can guarantee the flatness of the mouth of pipe.
3. double lever link gear hand-manipulated just can excise the excess metal pipe light, fast, and labor strength is low, and production efficiency is high.
